All Hot Rods are created from 8620 case hardened steel.  But, in addition to that, Hot Rods also undergo a special forging process which helps to improve grain flow as well as dimensional consistency.  That means a rod of uncompromising strength.  To improve fatigue durability, all Hot Rods rods are then shot peened.  This process, utilizing a stainless steel shot, helps to remove stress risers and creates smoothly blended radiuses.  In the end, a Hot Rods connecting rod is one of the most durable rods that enthusiasts and engine builders can buy.

However, a rod is only as good as its supporting parts and that’s why a Hot Rods kit features only the most advanced and durable bearings.  Case hardened and silver coated, the bearings are just as tough and reliable as the rods.  Even Hot Rods crank pins are subjected to the same rigorous standards as the rods and bearings.  Each crank pin is created from hot-rolled ASTM 4115 steel and case-hardened to a level of 58–62 Rc.
